Besides global warming, climate change is expected to result in (among others) an increased number of extreme precipitation events and a rising sea level. In the future, this can be the cause for an increased number of high river discharge events in combination with high water levels on the North Sea, which goes hand in hand with an increased...

Shanghai sea dikes are built to protect shorelines, factories, inland buildings and other vulnerable coastal areas against wave action and storm surge. For this reason, there is an urgent need to check whether sea dike in Shanghai can function well. The intuitive influences are sea level rise, severe storm surge, and land subsidence, which...

This research focuses on the estimation the failure probability of Shanghai sea-dikes system, taking into account several failure mechanisms. This method follows fully probabilistic approach, in which all relevant parameters for the resistances and the hydraulic loads vary according to specific distributions.

Design criteria for coastal defenses exposed to wave overtopping are usually assessed by mean overtopping discharges and maximum individual overtopping volumes. However, it is often difficult to give clear and precise limits of tolerable overtopping for all kinds of layouts. A few studies analyzed the relationship between wave overtopping...

Short duration bores in the coastal zone are generated by wave breaking in shallow water and mild foreshore conditions. In storm weather situations and for sea level rise scenarios, these bores approach the dike and interact with previously overtopped or reflected bores. Combined laser scanner and video measurements were used to study the...

During the last decades, the spectral wave period <i>T</i><sub>m-1,0</sub> has become accepted as a characteristic wave period when describing the hydraulic attack on coastal structures, especially over shallow foreshores. In this study, we derive an empirical prediction formula for <i>T</i><sub>m-1,0</sub> on shallow to extremely shallow...

Approximately 400 kilometres of Dutch sea dikes are protected by bituminous concrete revetments to prevent damage from erosion and repeated wave attacks during storms. The numerical analysis of sea dikes subjected to cyclic wave loading needs to consider the behaviour of the bituminous concrete revetment, and the behaviour of the subsoil...

Grass covers have been applied as an effective measure for protecting river levees and sea dikes. We conducted experiments to show how roots considerably improve the shear strength of soil on dike slopes. Roots of 1-year-old Bermuda and Carpet grass may increase the total shear strength of up to 20 kPa. Exposed to severe overtopping flow, dike...

During this research a method is developed for finding the cost optimal design of a sea dike when a probabilistic method is being applied and flexibility is allowed in the distribution of the total failure probability over the various failure mechanisms. A probabilistic model has been set up to calculate the cost optimal design for a sea dike...

Little is known about the strength of the land-side slopes of the Vietnamese sea dikes under overtopping attack. Some grass-covered slopes were tested by a wave overtopping simulator. The paper describes the simulator and presents the test results. The tested grass covers could withstand overtopping rates varying from 20 l/s to 100 l/s per meter...

The numerical simulation of wave attack on a sea dike with an asphalt concrete revetment during a severe storm is carried out using the dynamic Finite Element Method. When wave loads attack the revetment during such a storm, both the revetment and the underlying soil may be damaged. The two-phase flow equations are considered, to study the...

In the low-lying coastal regions coastal defense structures are usually designed with a main function to protect the hinterland from highly vulnerable of sea flooding. Sea dikes are usually the most common and important elements which form the coastal flood defense system. Sea dikes are designed at a pre-defined circumstance and requirement. For...

Apart from many ecological advantages, mangroves in front of a coastal defence may lower the construction and maintenance costs of the defence. Although mangroves have hardly any reducing effect on water levels (and on tsunami impact) mangroves may significantly reduce wave attack on a coastal dike, and in this way reduce the cost of a revetment...

The landware slopes of sea dikes in the north of Vietnam are steep and solely constructed by soil covered with grass due to the budget constraints and also the out-of-date design guidelines.The resistance against erosion due to wave overtopping of several grass covered slopes were tested with the Wave Overtopping Simulator to show if a slope...

This study further develops the method of probabilistic design and to address a knowledge gap in its application regarding safety and reliability, risk assessment and risk evaluation to the fields of flood defences. The thesis discusses: - a generic probabilistic design framework for assessing flood defence systems; - statistical techniques in...

This report is a compilation of facts and information that summarizes the present state of knowledge related to wave attack on the flood side of earthen levees. Particular emphasis was placed on the need for providing flood-side armoring (beyond the protection afforded by grass) for the New Orleans Hurricane & Storm Damage Risk Reduction System ...

Results showed that the existing model on erosion of clay with water-filled cracks (Führböter’s theory) which only considers cohesion as the soil strength is only applicable for certain conditions. The model should consider other resistant forces such as soil weight and pore pressures. From the tests on clay without water-filled cracks, it...

This report describes small-scaled experiments performed at Leichtweiß-Institute for Hydraulic Engineering and Water Resources, Technical University Braunschweig (LWI). The experiments have been conducted to investigate the development of dike breaches in homogeneous sand dikes with and without a clay layer. The used scaling factor was 1:10.The...
